7 Claims. (Cl. 178-24) This invention relates to a display cabinet for stock ticker information and more particularly to a mounting arrangement of a stock ticker and a projecting system within the cabinet.

The stock ticker cabinet of the present invention has a display screen in the upper portion of a front upstanding wall for displaying stock market quotations and other intelligence. In the use of this apparatus, the cabinet may be positioned in some offices with its front upstanding wall placed behind a Wall of a room so that only the display screen is visible through an aperture in this wall to viewers in an adjacent room thereby denying access to the interior of the cabinet from the front wall thereof; and in other oflices the back wall of the cabinet may be placed against a wall of the office thereby denying access to the interior of the cabinet through the back wall of the cab inet.

To facilitate servicing of a stock printer or ticker within an enclosed cabinet, it is desirable that the stock printer be movable to extend at least partially through an access opening in the wall of the cabinet while a service operation is being performed thereon. Thus, in a cabinet that may have either its front or rear Wall placed against a wall of an office, it is desirable that the printing assembly within the cabinet be capable of being extended through either of the two opposed access openings in the cabinet so that when one access opening is against a wall the printer assembly still may be serviced through the other access opening. The problem of affording access to a printer assembly within a cabinet is further complicated in that the projecting assembly is placed in close proximity to the record medium and in that the printing and projecting assemblies must be maintained in close registry or alignment with one another.

Accordingly, an object of the invention is to provide a stock ticker display cabinet which may have either of two Walls placed in close proximity to a wall of a room and having a recording mechanism therein capable of being extended through an access opening in either of the two walls of the cabinet.

A further object of the invention is to provide a cabinet for displaying stock market intelligence wherein a record ing mechanism therein can be extended at least partially through either one of two opposed access openings in opposed walls of the cabinet and wherein a projecting mechanism can be moved out of the path of movement of the recording mechanism.

A feature of the invention is the provision of a pivotally mounted printing and tape handling assembly that can be rotated to extend partially through each of a pair of opposed access openings in a wall of the cabinet and of a pivotally mounted projecting unit rotatable out of the path of movement of the printing assembly.

According to the preferred embodiment of the invention, a display cabinet totally encloses a printing and a projecting assembly and has a projecting screen in the upper portion of the front wall of the cabinet. The display cabinet has an access door in its front wall beneath the display screen and has a second access door in the opposed wall of the cabinet. The printing and tape handling assembly is pivotally mounted at one end to the base of the cabinet and includes a stock ticker or printer for printing stock market quotations on a record medium and also includes a record moving and winding apparatus ice for moving the record medium through the field of the projecting assembly and winding it on a take-up reel. An optical projection system in the cabinet includes a light source and a lens system for producing image bearing light containing the stock ticker intelligence and reflecting mirrors secured within the cabinet for reflecting the images to the display screen on the cabinet. The light source and lens system are mounted in a housing that is pivotally mounted within the cabinet and that is capable of being pivoted upwardly from its image producing position wherein it is in close proximity to the record medium and partially surrounding the record medium to an upward noninterfering position wherein it is out of the rotational path of movement of the printing assembly when the printing assembly is to be rotated through the access opening in the rear wall of the cabinet.

Other features and advantages of the invention will become apparent from the following detailed description when considered in conjunction with the accompanying drawings wherein:

FIG. 1 is a vertical sectional view of the display cabinet showing the mounting of the optical system therein;

FIG. 2 is a side elevational view on a reduced scale of the display cabinet with its rear upstanding wall positioned against a wall of a room;

FIG. 3 is a front elevational view also on a reduced scale of the cabinet showing the display screen and a front access door;

FIG. 4 is a sectional View taken along the line 4-4 of FIG. 1 in the direction of the arrows and showing the printing assembly pivotally mounted within the interior of the display cabinet, and

FIG. 5 is an enlarged view showing the printing assembly juxtaposed with the projecting assembly.

Referring now to the drawings and more particularly to FIG. 1, the display cabinet ltl is shown with its upstanding front wall 11 positioned against a room dividing wall 12 and having its upper screen bearing portion 13 extending through an aperture 14 in the room dividing wall 12. Thus, viewers in a room to the left of the room dividing wall 12 will see the screen bearing portion 13 of the display cabinet 10 and the stock designations and price quotations appearing on a viewing screen 15 in the cabinet 10.

Alternatively, as shown in FIG. 2, the display cabinet 19 may be placed to the left of the room dividing wall 12, i.e., in the same room as the viewers, and placed with its rear wall 16 in engagement with the room dividing wall 12. As thus situated, the display screen 15 is visible to the viewers within the room in which the display cabinet 1% is positioned.

As more clearly seen in FIGS. 3 and 4, the display cabinet 10 is provided with a front door 18 secured to the front wall 11 by a hinge 19 and similarly a rear door 20 is rotatably secured by a hinge 21 to the rear wall 16 of the display cabinet 10. Thus, with the display cabinet 10 positioned as shown in FIG. 1, viz., with the front door 18 positioned against the wall 12, access is available to the interior of the display cabinet 10 by pivoting the rear door 20 outwardly through the dotted line position shown in FIG. 4; and conversely, with the display cabinet 10 positioned as shown in FIG. 2, with the rear door 20 against the wall 12, access is afforded to the interior of the display cabinet 10 through the front door 18.

A printing assembly 24 and an optical system including a projection assembly 25 are housed within the interior of the display cabinet 10. The printing assembly 24 consists essentially of a supporting frame 29 having a stock ticker printer 26, and a tape take-up assembly 27 mounted thereon. The particular type of stock ticker for printing on the record medium is not critical to the instant invention, but may be of the type disclosed in United States Patent \a No. 1,821,110, issued to Morton et al. and likewise the type of take-up unit for the record medium is not critical to the present invention but may be of the type disclosed in United States Patent No. 1,973,839, issued to W. I. Zenner.

As shown herein, the stock ticker printer 26 has a supply reel 3% on which is wound a coil of transparent or translucent tape having its leading end extending to a printing position beneath a printing type wheel 31. The stock ticker printer 26 receives information in the form of electrical telegraph signals and converts this information to visible form in ink on a transparent or translucent tape 28. After passing through the printing position, the tape 28 passes around a pair of guide rollers 32, through a projecting station 33, and to a pair of cooperating driving rollers 34 to a take-up reel 35. As in the usual manner, the take-up assembly 27 moves the tape through the projecting station 33 in a smooth and continuous manner thereby preventing any jerking or sudden movements of the tape 28 that would appear as blurring movements of the information on the display screen 15.

The supporting frame 29 for the printing assembly 24 includes a pair of spaced longitudinal bars 33 and a plurality of lateral cross bars 37 extending between and securing together the spaced bars 38. A pair of gussets 36 are fastened as by welding to a tubular member 39 and extend outwardly in a V shape and are fastened to the undersides of the space bars 38. The tubular member 39 encircles a pivot stud 49 secured to the floor of the cabinet 1%. The pivot stud 40 acts as the pivotal center or axis about which the supporting frame 29 and the stock printer 26 and take-up assembly rotate as the tubular member 39 turns about the pivot stud 40.

As seen in FIG. 5, the right end of the supporting frame 29 rests on a supporting stand 42 secured to the floor 41 of the display cabinet 10.

As should be apparent, the printing assembly 24 can be rotated as a unit about pivot post 40 and, when rotated to either one of the two dotted line positions shown in FIG. 4, the printing assembly 24 will have a large portion thereof extending outwardly through an access opening in either the front wall 11 or rear wall 16 of the display cabinet 10. Relatively frequent access is needed to the printing assembly 24 in order to supply new rolls of tape to the printer 26 and to remove old rolls of tape accumulated on the take-up reel 35. To assure proper registry of the printing assembly 24 with respect to the projecting system, a matching register pin and slot arrangement (not shown) can be provided on the rotatable frame 29 and stationary supporting stand 42.

The optical projecting system consists of an image displaying screen 15, a pair of reflecting mirrors 44 and 45 and an image producing and projecting assembly 25. The reflecting mirrors 44 and 45 are pivotally mounted on pivot pins 46 fastened to the side walls 47 of the cabinet 10. Thus, the mirrors 44 and 45 can be adjusted so that the images will be properly reflected to the screen 15.

The projecting assembly has an outer housing 48 pivotally mounted on a rod 49 secured to the side walls of the cabinet. As seen in FIG. 1, the projecting assembly 25 is capable of being pivoted from its image producing position, shown in full lines, to its noninterfering position, shown in dotted lines, the latter position being out of the rotational path of movement of the printing assembly 24 to and through the access opening in the rear wall 16. To support the printing assembly 24, when the printing assembly 24 has been rotated through either of the access openings in the cabinet 10, a folded supporting leg 60 pivotally secured to a lateral crossbar 37 is released from its latched horizontal position by opening a spring latch 61 and then is pivoted into the vertical position to help support the weight of the printing assembly 24.

In order to project an image of the indicia printed on the tape, the projecting assembly 25 has a light source 59, a pair of condensing lenses 51, an objective lens 52 and a reflecting mirror 53. The light generated by the light source 50 is directed through the condensing lenses 51 beneath which passes the printed characters on the transparent record medium 28. It is preferred that the record medium be placed in close proximity to the condensing lenses S1. The image bearing light beam is received by the objective lens 52 which directs the light to reflecting mirrors 53, 45 and 44, in this sequence, and then on to the translucent display screen 15. The viewers of the screen 15 will see the stock ticker intelligence in enlarged form, readable from right to left, and in the normally upright position.

From the foregoing, the manner of servicing the printer assembly 24 should be manifest when the display cabinet 10 has either its front wall 11 against the room wall 12 or has its rear wall 16 against the room wall 12. With the rear wall 16 of the cabinet 10 in close proximity to the room wall 12, the front door 18 need only be opened and the printing assembly 24 rotated outwardly to its dotted line position of FIG. 4. With the front wall 11 of the cabinet 10 against the room wall 12, the projecting assembly 25 is rotated to its dotted line position shown in FIG. 1 and held or latched in this position by a means (not shown) while the printing assembly 24 is rotated about the pivot stud 40 through the now open, rear access door 21) whereupon the printing assembly 24 will be in the dotted line position shown in FIG. 4 and in this position affording access to either the stock ticker 26 or the tape take-up assembly 27.

Although only one embodiment of the invention is shown in the drawings and described in the foregoing specification, it will be understood that invention is not limited to the specific embodiment described, but is capable of modification and rearrangement and substitution of parts and elements without departing from the spirit of the invention.
